According to recent reports via a NeoGAF forum thread, a promo picture was found that may have revealed the official release date of Nintendo’s Mario Kart 8–the promo mentions a release window of April 2014 for the Wii U console.

The promo was made public via a Tweet from @DeSero, and a copy of the apparently official promo can be found below:

The promo apparently came by the way of an accidental slip-up in a European e-mail newsletter, and the April 2014 date fits loosely in line with the “Spring 2014″ release window for Mario Kart 8 announced by Nintendo. While we already knew that Mario Kart 8 would miss a 2013 release–the Wii U will be held up by titles like Pikmen 3, Super Mario 3D World and others–it will be interesting to see if Nintendo responds to this apparent reveal.

Mario Kart 8 will feature a massive character selection screen with many familiar and iconic faces from Nintendo’s flagship franchise, and also has a smattering of new maps, vehicles, and more. Mario Kart has always been one of Nintendo’s profitable series; Mario Kart for Nintendo’s previous Wii console has been a best-seller for Nintendo, selling over 30 million units worldwide.

In any case, be sure to check our gallery of screenshots below as well as Nintendo’s official E3 trailer for Mario Kart 8. For even more information, head on over to the game’s official website.
